title: [Second primary malignant neoplasms in patients treated in the Otolaryngology Clinic AM of Lodz in the years 1981-1989].
abstract: The incidence of multiple primary malignant tumours in 913 patients treated during 9 years for malignant neoplasms was investigated. In 24 (2.63%) cases second primary malignant neoplasm was diagnosed, mostly (in 19 cases-2.1%) it was correlated to cancer of larynx. In 18 cases (75% of all multiple tumours) neoplasms were metachronous, in 5-synchronous, and in one case--it was multifocal neoplasm (in both tonsils). In 3 patients three separate primary neoplasms were observed.
